Disrupted family reunification: Mental health, race, and state-level factors.

The children's mental health landscape is rapidly changing, and youth with mental health conditions (MHCs) are overrepresented in the child welfare system. Mental health is the largest unmet health need in child welfare, so MHCs may affect the likelihood of system reentry. Concerns regarding mental health contribute to calls for expanded supports, yet systems contact can also generate risk of continued child welfare involvement via surveillance. Still, we know little about how expanded supports at the state-level shape child welfare outcomes. Using the Adoption and Foster Care Analysis Reporting System (AFCARS), we examine the association between MHCs and system reentry within 36 months among youth who reunified with their families in 2016 (N = 41,860). We further examine whether this association varies across states and White, Black, and Latinx racial and ethnic groups via two- and three-way interactions. Results from multilevel models show that, net of individual and state-level factors, MHCs are associated with higher odds of reentry. This relationship is stronger for youth in states that expanded Medicaid by 2016 and with higher Medicaid/CHIP child participation rates. The results also show evidence of the moderating role of state-level factors, specifically student-to-school counselor ratio, diverging across racial and ethnic groups. Our results suggest a need for systems of care to better support youth mental health and counteract potential surveillance.

Prediction of Nonelective Central Venous Catheter Removal in Medically Complex Neonates.

INTRODUCTION: Central venous catheters (CVCs) are essential to neonatal care but associated with significant morbidity. Nonelective CVC removal (NER) is an inadequately studied outcome associated with increased morbidity, infant and family stress, and cost. This study describes prevalence and predictors of NER in infants admitted to a level IV neonatal intensive care unit and NER variation between peripherally inserted central catheters (PICCs), cutdown PICCs, and surgical CVCs. METHODS: In this study, we include patient and catheter data for infants admitted to a level IV neonatal intensive care unit (2010-2015). Demographic and clinical characteristics were compared using 1-way analysis of variance (ANOVA), Kruskal-Wallis, and chi-square tests for continuous, non-normally distributed continuous, and categorical variables, respectively. The association between NER due to complication and infant and catheter characteristics was assessed using generalized linear mixed models. RESULTS: Patient and catheter characteristics vary significantly by catheter type. The overall rate of NER is 15% (17% PICCs, 13% cutdown PICCs, and 19% surgical CVCs). The most common indications for NER are catheter breakage, blood stream infection(BSI)/central line-associated blood stream infection(CLABSI), catheter malposition, mechanical obstruction, and extravasation. Birth weight, patient diagnosis, catheter dwell time, and concurrent catheters are associated with increased odds of NER. CONCLUSIONS: Patient risk factors and potentially modifiable catheter characteristics, including catheter dwell time and concurrent catheters, are associated with increased NER. As NER is associated with a broad spectrum of adverse outcomes, we propose a quality improvement strategy to risk stratify patients and reduce exposure to high-risk, modifiable catheter characteristics.

Association of Prenatal Exposure to Population-Wide Folic Acid Fortification With Altered Cerebral Cortex Maturation in Youths.

Importance: Presently, 81 countries mandate the fortification of grain products with folic acid to lessen the risk of neural tube defects in the developing fetus. Epidemiologic data on severe mental illness suggest potentially broader effects of prenatal folate exposure on postnatal brain development, but this link remains unsubstantiated by biological evidence. Objective: To evaluate associations among fetal folic acid exposure, cortical maturation, and psychiatric risk in youths. Design, Setting, and Participants: A retrospective, observational clinical cohort study was conducted at Massachusetts General Hospital (MGH) among 292 youths 8 to 18 years of age born between January 1993 and December 2001 (inclusive of folic acid fortification rollout ±3.5 years) with normative results of clinical magnetic resonance imaging, divided into 3 age-matched groups based on birthdate and related level of prenatal folic acid fortification exposure (none, partial, or full). Magnetic resonance imaging was performed between January 2005 and March 2015. Two independent, observational, community-based cohorts (Philadelphia Neurodevelopmental Cohort [PNC] and National Institutes of Health Magnetic Resonance Imaging Study of Normal Brain Development [NIH]) comprising 1078 youths 8 to 18 years of age born throughout (PNC, 1992-2003) or before (NIH, 1983-1995) the rollout of folic acid fortification were studied for replication, clinical extension, and specificity. Statistical analysis was conducted from 2015 to 2018. Exposures: United States-mandated grain product fortification with folic acid, introduced in late 1996 and fully in effect by mid-1997. Main Outcomes and Measures: Differences in cortical thickness among nonexposed, partially exposed, and fully exposed youths (MGH) and underlying associations between age and cortical thickness (all cohorts). Analysis of the PNC cohort also examined the association of age-cortical thickness slopes with the odds of psychotic symptoms. Results: The MGH cohort (139 girls and 153 boys; mean [SD] age, 13.3 [2.3] years) demonstrated exposure-associated cortical thickness increases in bilateral frontal and temporal regions (9.9% to 11.6%; corrected P < .001 to P = .03) and emergence of quadratic (delayed) age-associated thinning in temporal and parietal regions (ß = -11.1 to -13.9; corrected P = .002). The contemporaneous PNC cohort (417 girls and 444 boys; mean [SD] age, 13.5 [2.7] years) also exhibited exposure-associated delays of cortical thinning (ß = -1.59 to -1.73; corrected P < .001 to P = .02), located in similar regions and with similar durations of delay as in the MGH cohort. Flatter thinning profiles in frontal, temporal, and parietal regions were associated with lower odds of psychosis spectrum symptoms in the PNC cohort (odds ratio, 0.37-0.59; corrected P < .05). All identified regions displayed earlier thinning in the nonexposed NIH cohort (118 girls and 99 boys; mean [SD] age, 13.3 [2.6] years). Conclusions and Relevance: The results of this study suggest an association between gestational exposure to fortification of grain products with folic acid and altered cortical development and, in turn, with reduction in the risk of psychosis in youths.

Hemoglobin thresholds for transfusion in pediatric patients at a large academic health center.

BACKGROUND: Although prior studies support the use of a hemoglobin (Hb) transfusion trigger of 7 to 8 g/dL for most hospitalized adults, there are few studies in pediatric populations. We therefore investigated transfusion practices and Hb triggers in hospitalized children. STUDY DESIGN AND METHODS: We performed a historical cohort study comparing transfusion practices in hospitalized children by service within a single academic institution. Blood utilization data from transfused patients (n = 3370) were obtained from electronic records over 4 years. Hb triggers and posttransfusion Hb levels were defined as the lowest and last Hb measured during hospital stay, respectively, in transfused patients. The mean and percentile distribution for Hb triggers were compared to the evidence-based restrictive transfusion threshold of 7 g/dL. RESULTS: Mean Hb triggers were above the restrictive trigger (7 g/dL) for eight of 12 pediatric services. Among all of the services, there were significant differences between the mean Hb triggers (>2.5 g/dL, p<0.0001) and between the posttransfusion Hb levels (>3 g/dL, p < 0.0001). The variation between the 10th and 90th percentiles for triggers (up to 4 g/dL, p < 0.0001) and posttransfusion Hb levels (up to 6 g/dL, p < 0.0001) were significant. Depending on the service, between 25 and 90% of transfused patients had Hb triggers higher than the restrictive range. CONCLUSIONS: Red blood cell (RBC) transfusion therapy varies significantly in hospitalized children with mean Hb triggers above a restrictive threshold for most services. Our findings suggest that transfusions may be overused and that implementing a restrictive transfusion strategy could decrease the use of RBC transfusions, thereby reducing the associated risks and costs.
